Tessenderlo

What Tessenderlo does

Tessenderlo Group nv is a diversified Belgian industrial group headquartered in Brussels, founded in 1919 and listed on Euronext Brussels (TESB). The company operates through five business segments — Agro (Tessenderlo Kerley, Tiger-Sul, Violleau for crop nutrients and crop protection), Bio-valorization (PB Leiner for gelatin and collagen peptides and Akiolis for rendering, proteins and fats), Industrial Solutions (DYKA Group plastic piping systems, Kuhlmann Europe specialty chemicals, moleko), Machines & Technologies (Picanol weaving machines, Proferro foundry, Psicontrol electronics, Melotte 3D metal printing), and T-Power (a 425 MW gas-fired combined cycle power plant). Tessenderlo serves enterprise customers across agriculture, food, pharmaceutical, construction, water treatment, textile and energy end markets in over 100 countries, with a global team of more than 7,000 employees.

The group generates revenue predominantly through one-time sales of industrial and specialty chemical products (fertilizers, gelatin, collagen peptides, plastic piping systems, weaving machines, electronics, power) under B2B quote-based pricing, supplemented by a 15-year tolling arrangement with RWE Group for T-Power. Technology differentiation rests on proprietary specialty chemistry processes — including cold-soluble gelatin (CRYOGEL, the first to market), INSTAGEL instant gelatin, patent-pending TEXTURA texturizers, advanced membrane electrolysis at Loos (France), and a circular bio-valorization model that converts animal by-products from Akiolis rendering into high-margin gelatin and collagen peptides for food, pharmaceutical and biomedical customers.

Following its 2023 combination with Picanol Group and the December 2025 agreement to merge collagen/gelatin assets with Darling Ingredients into a joint venture (Nexida) targeting roughly $1.5 billion in annual revenue and ~30% of global collagen supply, Tessenderlo has reshaped into a more focused specialty industrial group. The 2026 acquisition of a minority stake in FMC Corporation ($400M, ~20%) and ongoing Agro-segment bolt-ons (Tiger-Sul, Cinis SOP plant) signal continued capital deployment into specialty chemistry and bio-based adjacencies.
